Since both sensible and latent heat co-exist at the fin surfaces for dehumidifying conditions and the condensing phenomenon contributes a lot to the air side heat transfer. The goal of this project is to establish the numerical model for simulating the simultaneous heat and mass transfer in the fin-and-tube heat exchangers under dehumidifying conditions.
In this study, not only the new model has accounted for the mass transfer between the water vapor in the moist air and the condensed water liquid but also the direct condensation model of water vapor is provided which can bring the numerical simulation model a step closer to the actual simultaneous heat and mass transfer in the wet conditions. The numerical simulation model will be used to analyze the relations of different fin efficiencies under dehumidifying conditions as well as the effects of fin pitch, tube rows, inlet air velocity and relative humidity.
More information will be updated with project processing.
